Array and for loop - please help!

Hello,

I just want to create an array of numbers counting from 1 to a given number.

At the moment I have the for loop running like this:

var i=0;
for (i=1;i<=10;i++)
{
if (i == 1)
{
document.write(i);
} else {
document.write(", " + i);
}
}

This outputs 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

How can I put this output into this variable: 'var ids' so I get out

var ids= [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

I'm a bit of a novice so any help would be great! :)

This should move you forward:-


<div id = "results"></div>

<script type = "text/javascript">

var ids = new Array();
var string = "";
for (var i = 0; i <10; i++) {
ids[i] = i+1;
string = string + " " + ids[i];
}
alert (ids);
alert (string);
document.getElementById("results").innerHTML = string;

</script>

Note that the index of an array starts at 0, so here you need to make the 0th value = 1 by ids[i] = i+1;

A variant would be:-

<script type = "text/javascript">

var ids = new Array();
var string = "";
for (var i = 0; i <=10; i++) {
ids[i] = i;
if (i > 0) {
string = string + " " + ids[i];
}
}
alert (ids);
alert (string);
document.getElementById("results").innerHTML = string;

</script>

Brilliant, worked perfectly - thanks! :)

This is great, Philip. I was having trouble with something similar, and as usual you make it seem so simple.
